Boilers

These systems typically are gas- or oil-fired, and circulate hot water through a system of pipes in the floor, baseboard heating units, or radiators. A hot-water heating system can be very comfortable. The radiant heat provides warmth without the draft created by air circulation. If you’re considering a hot water heating system, Focus recommends a 90 percent AFUE modulating boiler with an outdoor temperature reset to maximize energy savings and comfort.
